Albian-Cenomanian arenites overlying Dinaric platform carbonates contain detritus derived from continental and ophiolitic rocks

Albian-Cenomanian sediments of the inner marginal portion of carbonate Dinarides in northwesten Croatia are represented by turbidites and pelagites. We have studied heavy-mineral associations and non-carbonate particle composition from Albian-Cenomanian arenites in order to obtain data on relevant source rocks. The heavy mineral associations are highly dominated by the ultrastable minerals. However, chromspinel grains make 6-24 percent. Non-carbonate paticles include lithoclasts of low-grade metamorphic, and subordinately sediments, volcanics and mafic/ultramafic rocks. These data reflect a pre-Albian deformation in the areas situated to the NE of the basin.
